App Introduction

App Introduction


The SUN2000 app (app for short) is a mobile phone app that communicates with the solar inverter over a WLAN module, a Bluetooth module or a USB data cable to allow for querying alarms, setting parameters, and performing routine maintenance as an easy-to-use maintenance platform.

Connection Mode

After the DC or AC side of the solar inverter is powered on, the app can connect to it either over a WLAN module, a Bluetooth module or a USB data cable.

  • Over a WLAN module: The USB-Adapter2000-C WLAN module is supported.
  • Over a Bluetooth module: The USB-Adapter2000-B Bluetooth module is supported.
  • Over a USB data cable: The USB 2.0 port is supported. Use the USB data cable delivered with the mobile phone.
  • Requirements for the mobile phone operating system: Android 4.0 or later.
  • Recommended phone brands: Huawei, Samsung.

The app snapshots provided in this document correspond to the SUN2000 app (this app is available only on Android phones currently). The snapshots are for reference only.

  • The configurable parameters of the solar inverter vary with the device model and grid code.
  • Changing the grid code may restore some parameters to factory defaults. Check whether the previously set parameters are affected.
  • The parameter names, value ranges, and default values are subject to change.
  • Delivering a reset, factory reset, shutdown, or upgrade command to the solar inverters may cause power grid connection failure, which affects the energy yield.
  • Only professionals are allowed to set the grid parameters, protection parameters, feature parameters, power adjustment parameters, and grid-tied point control parameters of the solar inverters. If the grid parameters, protection parameters, and feature parameters are incorrectly set, the solar inverters may not connect to the power grid. If the power adjustment parameters and grid-tied point control parameters are incorrectly set, the solar inverters may not connect to the power grid as required. In these cases, the energy yield will be affected.

User Operation Permissions

The user accounts that can log in to the app are classified into common users, special users, and advanced users based on the responsibilities of PV plant operation personnel.

  • Common user: Has the permission of viewing data and setting user parameters.
  • Advanced user: Has the permission of viewing data, setting functional parameters, and maintaining devices.
  • Special user: Has the permissions of viewing solar inverter data, setting grid related parameters, and maintaining devices (including starting and shutting down the solar inverter, restoring factory defaults, and upgrading devices).

File save path is displayed only on the Android app.
